To all whom it may concern:

Be it known that I, FRANK MAGIDSON, a resident of Pittsburg, in the county of Allegheny and State of Penns lvania, have invented certain new and use 111 Im rovements in Coin-Controlled Apparatus, 0 which the following is a specification.

This invention relates to that type of electric motor driven mechanism in which the closing of the motor circuit is controlled by a coin or check inserted by the person desiring the service of the mechanism actuated by the motor, and the primar ob'ect is to provide -an improved and hig y e cient means for .15 effecting the closing of the circuit.

A further object is to provide improved means for transmittin motion from the motor to the controlling mechanism for actuating the latter to open the motor circuit and hold it open upon the com letion of.

the service; also to improve the evice. for closin the motor circuit switch.

StilIa further object is to provide an improved push button switch or contact of such form as to insure the positive closing of the starting circuit when the button is pressed. WVhile the improvement may be employed in various forms of apparatus, it is designed with special reference to the requirements of automatic shoe polishing m-achmes, and for this reason means are provided for securing two operations of the machine from a single com.

In the accompanying drawings, Figure 1 is an elevation of the improved mechanism,

shown partly in diagram. Figs. 2 and 3 are edge views showing, respectively, the motor circuit switch open and closed. 4 is a section of the push button switch. Figs. 5

and 6 are face views of the coin-holding devices. Fig. 7 is a sectional plan taken on line 77 of Fig. 4. Figs 8 and 9 are detail views of the coin contact.

Referring to the drawings, 2 designates the motor and 3 the motor circuit, with switch 4 in the latter havin the pivoted s ringclosed blade 5. The lade is preferabiy disposed vertically, and pivoted to its lower end is the vertically oscillatin arm 6. The inner to end 7 of this arm is o arrow shape and formed with depending shoulder 8, while behind the shou der is the upward recess 9 in the under edge of the arm.

by the motor, as will presently be described, and secured to and insulated from the shaft is finger 11. Inner end 7 of arm 6 is normally in the path of this finger,;so that the latter advances beneath the arrow-she ed end 7 and engages shoulder 8, and t us m'oves arm 6 and switch-blade 5 outward, thus opening the switch, and with the power thus s u-t off, shaft 10 and finger 11 stop in the position shownin Fig. 2 and hold the switch open. Thus, the switch is opened and held open each time shaft 10 makes a complete rotation.

In the mechanism here shown for effecting the intermittent movement of shaft 10, a shaft 12 is geared to and rotated by the motor. Secured to this shaft is finger 13 which engages, successively, the teeth 14 of wheel 14secured to timing shaft 10, the latter being advanced a certain portion of its intermittent rotation on each complete revolution of shaft 12. The rapidity of this intermittent movement is of course determined by the number of teeth on wheel .14, and thus a complete rotation may be im arted to shaft 10 during either a greater -oress number of rotations of finger '13, as the particular form of machine to which the invention is applied may re uire.

will now describe the preferred means I or closing the switch and starting the motor.

15 designates an auxiliary or starting circuit which by preference is merely a branch of the main circuit. This auxiliary circuit has two interruptions, one adapted to be closed by blade 5 of the motor-circuit switch and the other by a ushbutton switch mechanism 16, present y to be described. As to the first mentioned interruption, one terminal 18 of the auxiliary circuit is connected to the circuit feed wire 3', and the other terminal 18' is secured to the sprin contact 19 which projects into the path of ger 11. Within auxiliary circuit 15 is ma et 20 having its armature 21 provided w1th a hammer-like extremity 22 10 is a timing shaft intermittently moved pressure of its s ring,

positioned over the outer end of pivoted arm 6. When switch-blade 5 is in open position with-the motor circuit open, the interruption in the auxiliary circuit is closed through blade 5, arm 6, 'finger 11, and spring contact 19, the latter being at such time in engagement with and its extremity 19 pressed ontwardly by finger 11. Auxiliary circuit 15 is however normally open at the push-button or controlling switch 16. Upon closing the latter, as when the user of the machine is ready for the operation, the circuit is closed. This results in the energizing of magnet 20, and the resulting vertical vibrations of hammer-armature 21 depresses the outer end of latch-arm 6, thereby raising shoulder 8 out of engagement wit finger 11 and permitting switch-blade 5 to close under; the thereby closing the motor circuit an starting the motor. Arm 6 moves inward with the switch blade, with recess 9 over finger 11, as in Fig. 3, thus opening auxiliary circuit 15. Thus, the instant. the auxiliary circuit is closed it is automatically opened and the movement which opens it closes the motor circuit.

The action is so quickpractically instantaneous that the magnet coils cannot become injuriously heated. Switch blade 5 remains closed and the motor and motor driven mechanism continue to operate until finger 11 has completed its circular travel, when it engages end 7 of arm 6 and shoulder 8 and moves blade 5 to open position, as above described, thus openin the motor circuit, and at the same time closing the interru tion in the auxiliary circuit and placing' t e parts in position for again starting when the auxiliary circuit is closed by switch 16.

Referring now to the controlling switch mechanism 16, the sameis preferably of push-button form which is a convenient type to be operated, although obviously the invention is not limited thereto. In the present adaptation, 23 indicates a portion of casing which incloses the mechanism, and located therein is the coin chute 24 leading to a coin receptacle, not shown. Within and interrupting the coin passage are the coin holders 26 and 27 arranged one beneath the other and pivoted to oscillate vertically, the outer ends of the holders being connected' by link 28, with said outer ends held normally depressed and the inner or coinholding ends raised'in coinsstopping position by spring 29. When the coin is inserted its movement is stop ed and it is held by holder 26, and while in t is position the mechanism isstarted for the first operation, and at the completion of the latter the holders are oscillated and the coin permitted to drop from holder 26 to holder 27, when its movement is again stopped and itls held until the second o eration of the machine has been starte Holders26 and 27 are oscillated by the vertically swinging arm 30,"this arm being actuated by the trip device '31 on shaft 10. Fig. 5 illustrates the'c'oin or check C operatively held by the first holder-26, from which position the holders are oscillated to the full line position of Fig. 6, permitting the coin to drop into engagement with the upper extremity 27 of holder 27. And when spring 29 returnsthe holders to the dotted line position of Fig. 6,-the coin rolls down and is held by the lower extremity of the holder, ready for the second circuit-closing operation. Circuit 15 has one terminal connected at 32 with the metallic coin chute 24, while the other terminal 33 of the circuit interruption is connected to switch-head 34 having the push stem 25 exposed through casing 23. The switch is located at one side of the coin passage, and head 34 carries two stems 35 and 36 movable through insulated block 37 toward the coin stopping positions, being held normally out of engagement with the coin by springs 38. At the inner extremity of each of stems 35 and 36 is an independentlymovable coin contact 39, having a pin and slot connection 40 with the tubular extremity of the stem and held normally projectwl by spring 41. Each of stems 35 and 36 is shouldered at 42 and engages the face block 37 before the stem extremity can engage the coin, so that the only pressure on the latter emanates fromthe light spring 41, and such pressure is not su'liicient to resist the gravity and rolling action of the coin when holders 26 and 27 are oscillated. If it were possible to push stems 35 and 36 into direct engagement with the coin, the latter would be held and the machine kept running indefinitely by not releasing the push-button.

In operation, the inserted coin is first held by holder 26 opposite contact 35, and when the operator desires the mechanism to start, he merely presses push button 25 which forces inward stem 35 and engages its contact 39 with the side face of the coin, at the same time pressing the coin against the wall of coin chute 24 to which'the starting circuit 15 is connected. Thus, a positive and thoroughly effective closing of the circuit is accomplished, the action being far more certain than though gravity were depended upon for holding the coin in engagement with two contacts, as has been proposed heretofore. Upon the completion of the first operation, as when one shoe has been cleaned and polished, the coin has already been released from its first position and is stopped by holder 27 op osite the lower contact stem 36, and it is on y necessary for the operator to again press the button for securing another complete operation of the mechanism, as for cleaning and polishing the second shoe. During this second operation the coin holding mechanism is actuated to release the coin and permit it to drop from circuit closing position into a receptacle to which the chute leads.
